I have the systema M120 box and i am shooting at roughly 375ish fps. The box doesn't fit into a systema body (odd eh?) without sanding the inside of the upper reciever. The box itself is a bit wider than a TM and no doubt SRC. Also, i tried to put my systema box into my SRC and i just couldn't make it work. It was so godamn tight and i was only able to get the upper reciever on about 1/4 of the way. Some sanding is required.
Have fun... :-)
*Note- the systema box fits into G&P bodies EXTREMELY nice...
